PoS miners do not create new coins but instead only validate transactions.

PoS miners receive transaction fees instead of mining rewards.

PoS users can buy their PoS coins such as Qtum or Stratis in exchanges. In order to increase forging profits, they can participate in Pool of Stake.

The PSK utility token is on the Ethereum blockchain so users can keep PSK tokens in their Ethereum wallet. IOU tokens exclusively serve the purpose of declaring initial PoS coin ownership. IOU tokens cannot be traded, not even among PSK community members. PSK will act as a regular node on PoS coins.
